javascript - 在 Google Apps 脚本中循环数组

Question

我正在尝试为数组编写循环，但收到无效字符串错误。

如果关键字=“间皮瘤|seo”

function json(keyword) {
  var jsondata = UrlFetchApp.fetch("http://api.grepwords.com/lookup?apikey=carterq="+keyword);
  var object = Utilities.jsonParse(jsondata.getContentText());

  var results = Array("Error", "Error", "Error", "Error");

  for (var i = 0; i < object.length; i++) {

  results[0] = object[0].cpc;
  results[1] = object[0].cmp;
  results[2] = object[0].lms;
  results[3] = object[0].m1;
  }

  return results;
}

有什么想法吗？

您的引用错误来自此行:

var jsondata = UrlFetchApp.fetch("http://api.grepwords.com/lookup?apikey=carter&q="+keyword);

从上面的代码中，这是您使用“关键字”的唯一时刻。您确定它返回正确的信息吗？如果确实如此，您是否考虑过您的循环？

假设您的 var object = Utilities.jsonParse(jsondata.getContentText()); 返回以下内容:

  var object = [
      {cpc: 'test1', cmp: 'test2', lms: 'test3', m1: 'test4'},
      {cpc: 'test5', cmp: 'test6', lms: 'test7', m1: 'test8'},
      {cpc: 'test9', cmp: 'test10', lms: 'test11', m1: 'test12'}
  ];

我们使用你的循环:

  for (var i = 0; i < object.length; i++) {

  results[0] = object[0].cpc;
  results[1] = object[0].cmp;
  results[2] = object[0].lms;
  results[3] = object[0].m1;
  }

你确实意识到你从不使用“i”吗？并且在每次循环后用相同的内容覆盖结果？您确定想要这个吗？

function somefunc() {

  var object = [
      {cpc: 'test1', cmp: 'test2', lms: 'test3', m1: 'test4'},
      {cpc: 'test5', cmp: 'test6', lms: 'test7', m1: 'test8'},
      {cpc: 'test9', cmp: 'test10', lms: 'test11', m1: 'test12'}
  ];
  var results = Array("Error", "Error", "Error", "Error");

  if (object[0] != undefined)
  {
  results[0] = object[0].cpc;
  results[1] = object[0].cmp;
  results[2] = object[0].lms;
  results[3] = object[0].m1;
  }

  for (var i = 0; i < object.length; i++) {

  results[0] = object[0].cpc;
  results[1] = object[0].cmp;
  results[2] = object[0].lms;
  results[3] = object[0].m1;
  }

  return results;
}

console.log(somefunc());
